Abstract: The interlacing degree serves as an important indicator for evaluating the performance of filament yarns and fabrics, typically detected manually in production workshop. To address the issues of high false detection rates in manual inspection, a parallel detection method for filament yarn interlacing degree based on semantic information enhancement is proposed. Firstly, to improve the recognition accuracy of interlacing nodes in a filament yarn, an improved backbone architecture based on MobileNetV2 is used for semantic information extraction to improve the computational speed of model. Building upon the proposed backbone architecture, semantic information enhancement module and multilevel feature dilated module are designed to process the feature information of the backbone architecture. Meanwhile, a pixel-level attention mask is designed to weight and fuse the feature, in order to improve the accuracy of interlacing degree detection. Then, based on the proposed enhancement algorithm for semantic information, a parallel detection method of interlacing degree is designed to achieve batch calculation for interlacing degree of multiple filament yarns. The algorithm is used to detect interlacing node, while connected domain analysis and mask extraction are used for parallel detection to extract independent regions of each filament yarn within the field. The parallel detection results are then fused to accurately obtain the interlacing degree detection results for each filament yarn. To validate the effectiveness of the proposed method, a synthetic filament yarn dataset is established using a self-developed interlacing degree detection device, and experimental verification is conducted. The results demonstrate that the proposed method can effectively improve the accuracy of detection.
